Fireproof and water proof photovoltaic coiled material and method for preparing same

Abstract

The invention discloses a fireproof and water proof photovoltaic coiled material. The fireproof and water proof photovoltaic coiled material is of a layer-shaped structure and is composed of a waterproof coiled material lining and a flexible photovoltaic module from bottom to top, wherein a high-tenacity glass fiber reinforced flame retardant non-woven fabric is used as a base for the waterproof coiled material lining, flame-retardant polymer modified cement mortar is arranged on the two faces of the base through blade coating, and the solar photovoltaic module sequentially comprises a flexible thin-film photovoltaic cell pack, a film layer and a coating layer from bottom to top. The invention further discloses a method for preparing the fireproof and water proof photovoltaic coiled material. The method includes the following steps of firstly, preparing the waterproof coiled material lining; secondly, preparing the photovoltaic cell pack; thirdly, conducting combining and packaging. According to the fireproof and water proof photovoltaic coiled material, the laying and construction method is simple, the waterproof coiled material can be bonded to the roof of a building in a cold mode through polymer dry-mixed mortar bonders which have a fire prevention function, the fireproof and water proof photovoltaic coiled material is free of fire heating, environmentally friendly, easy to operate and low in comprehensive cost, and the building integrated photovoltaics which integrates multiple functions such as the waterproofing function, the fire prevention function, the decoration function and the photovoltaic power generation function is obtained.

Description

technical field [0001] The invention relates to the fields of building energy saving and photoelectric buildings, in particular to a photovoltaic waterproof coiled material integrating multiple functions of fire prevention, waterproof and photovoltaic power generation and a preparation method thereof. Background technique [0002] The building roof is the preferred location for photovoltaic power generation in buildings, and its photovoltaic power generation components mainly include crystalline silicon photovoltaic panels and amorphous silicon photovoltaic thin film battery coils. There are two ways to fix the crystalline silicon photovoltaic panel on the roof of the building. One is to use its own weight or increase the pressure to place it directly on the roof. Due to the heavy load, it cannot be applied on light roofs and long-span roofs; in addition, it is not easy to apply on exposed waterproof roofs, because the component force of the obliquely placed pressure battery...

Problems solved by technology

However, there are still the following problems in the engineering application of this technology: first, the on-site wet operation is greatly affected by environmental and human factors, material waste, high labor costs, and prone to quality problems; second, the current TPO single-layer polymer waterproof membrane, improved The high price and poor fire resistance of permanent asphalt waterproofing membranes make it difficult to meet the country's increasingly stringent fire safety requirements for roof waterproofing materials.
